Binary Watch Face

Binary Watch Face shows the time the way a computer counts: in bits. Every lit dot adds its value; the sum is the time.

Free:

• The classic binary-coded look: one column per digit, four dots each

• Follows your watch's 12/24-hour setting

• Battery-friendly always-on mode with slim rings

Pro, a one-time purchase on your phone or your watch, unlocks every option in the watch face editor:

• Three layouts: Grid and Classic (one column per digit) or Rows (plain binary, one row each for hours, minutes and seconds)

• Optional seconds that tick along in an extra pair of columns or a third row

• 16 colour themes, including multi-colour themes with separate colours for hours, minutes and seconds

• Five backgrounds, four dot shapes (circle, rounded, square, bar) and three styles for unlit dots

• Learning aids: bit values and the decimal time next to the dots, until you read binary at a glance

• Two complications for the date, battery, steps, weather or any other data

• Two always-on styles

Built with Google's Watch Face Format: light on memory and battery. The watch app installs the watch face for you; open it and tap "Use this watch face".

Requires a watch with Wear OS 6 or newer. The phone app shows a live preview of every option, explains how to read the face and opens it in the Play Store on your watch.
